Alex Vesia missed the World Series due to the death of his baby daughter:

“Our little angel we love you forever & you’re with us always,” Vesia and his wife, Kayla, said on Instagram in a post that included a picture of an infant holding hands with adults. “Our beautiful daughter went to heaven Sunday October 26th. There are no words to describe the pain we’re going through but we hold her in our hearts and cherish every second we had with her.”

My thoughts are with his family at this sad time.
